SAFETY-GUIDE.

Specification of Letters Patent.

Patented Aug. 2a, 1911.

Application led March 6, 1911. Serial No. 512,489.

To all whom it may concern:

Be it known that I, PATRICK SHEEHAN, a citizen of the United States,residing at 316 East Ninetieth street, New York city, New York, haveinvented a new and useful Improvement in Safety-Guides, of which thefollowing is a specification.

This invention relates to elevator appliances and has for its object theprevention of injury to employees and damage to property incident to theuse of hoisting elevators in the erection of buildings.

In erecting a building it is the practice to carry the concrete, plasterand other materials in wheel-barrows, and the wheel-barrows are raisedfrom the basement to the floor desired by a lift or elevator. Thiselevator is operated from a hoisting engine by signals, and quick actionis required in deposit-ing the wheel-barrows on the lift, giving thesignal, and proceeding with the hoist. The elevator itself isnecessarily compact, and it frequently happens that wheel-barrows areplaced on the elevator platform or car so that the handles at the rear,or the wheel in front, projects over the edge of the elevator platformor car so thatwhen the latter is raised the wheel-barrow or elevator orboth are wrecked in passing a iioor above, and the workmen arefrequently injured as well. Various attempts have been made to overcomethis evil and to provide some sat-isfactory means for preventing theover or under positioning of the wheel-barrow. But on account of thefact that the wheel-barrows are rolled onto and off the lift half thetime from one side and half the time from the other in the course oferection of the building and the various floors thereof, it i's obviousthat no mere stop or wall forming part of the elevator can be used. Itis further clear that the temporary character of the whole installationwill not permit of any expensive attachments.

It is the purpose of my invention to provide what I term an improvedsafety guide and which is a device or attachment which will permit theproper positioning of wheelbarrows on an elevator platform or car, whichwill permit the wheel-barrows to be rolled on or olf in eitherdirection, which will permit the wheel-barrows to be faced in eitherdirection, which is very easy to attach, and which is cheap to constructand durable.

With the foregoing in view, the invention consists in the improvedsafety guide as hereinafter set forth.

In the drawings, Figure l, illustrates in side elevation the use of asafety guide embodying the principles of my invention; Fig. 2, is a topplan view; Fig. 3, is a side elevation; Fig. t, is a vertical section;Fig. 5, is a bottom plan view; Fig. 6 is a side view of the bar; Fig. 7,is an end view of the same; Fig. 8, illustrates a gib screw which may beemployed with my invention.

lIhe invention will include a metal casting or body having a hoppershaped pocket on the upper side and means by which the casting isattached to the floor of the elevator platform.

l denotes broadly the casting as a whole, and 2 denotes the hoppershaped pocket on the upper side thereof. The construction of the pocketmay vary somewhat in practice, but in the best constructions willinclude certain features or characteristics which I will later describe.

The casting has a considerably greater length than its widthwisedimension and the upper surface is inclined downward from the pockettoward either end by a comparatively long gradual incline 3 so that thelegs of the wheel-barrows tend to run naturally up the inclines and dropinto the pockets, and further so that the workmen hastening across thecar from either side will not trip over the safety guide. Also I preferto roughen the surface of the incline so that it will constitute afoot-hold, and the best form is that illustrated in which a series ofinclined teeth 4 pointed upward give the best protection against thefoot of the workmen slipping down the incline and vat the same timeoffer a minimum obstruction to the wheel-barrow legs riding up theincline, or the foot of the 'workman likely to trip thereon.

The bottom of thel casting is ribbed in the interests of strength andlightness. The form of the bottom also coperates with a longitudinaladjustment which I provide,

and by means of which the safety guide is equally adapted for use withwheel-barrows moved onto the lift from either side. Referring to Fig. 1,the outline of an ordinary wheel-,barrow is shown inabout the way itwillbeplacedupona'lift From this diagram it will be seen that thertwolegs of the wheel-barrow fall on a line somewhat back of acentral-'plane so that vif the wheel-barrow is pushed ontol the elevatorfrom; the opposite sidethe legswill be as much on such l other side. of;the fcentral plane. total difference in. ositionwamountsto per.- haps 8inches in .ordinary practice. Accordingly I provide a means foradjustingmy safety guide a sufficient.l distance tozaccominodate thevabove two p ositions offa wheelbarrow. In the best constructionsembodying the-invention,.there wil-lbe provided a bar 5 of preferablysquare transverse section and having holes by which itis screwed to thefloorrofthe lift.- Thel undersidee of the safety yguide is recessed witha groove. `61 hav` Y ing a. transverse section corresponding` to thatofthe bar; Means will be provided for securing the safetyf guide to thebar` in any positionof longitudinal adjustment. Ordinarily there will beholes 7cored laterally in the casting near eachcendithereof and eX-tending over ythe bar sothat gib screws 8 may be inserted in thecoredholes with the hooked-over ends 9 engaging the bar 5.

10. denotes nuts by whichfthe gib screws are tightened.- The.l gibscrews may be located inthe holes onzeithen side', ofthe `bar as ismost. convenient, and do not preventthe removal of the entire safetyguide fromthe elevator platform when desired.I

11 denotes screw holes by which the safety.

guide mayI be vpermanently attachedtov the floor of an eleva-torplatform in case the longitudinal adjustment isnot required.

I have already referred to the pockets 2 which have a widthrsufficientto accommo Thel `casting in the interest-s of strength and lightness. Inthe approved construction the casting Vwill have a bottom face asparticularlyr shown in Fig. 5, with passages 15 grooved therein andrecesses 16, and the middle or main portion of the casting,V will have acontour corresponding to the upper surface. There will however bestrengthening ribs 17 and 18 in order to have the high degree ofrigidityzandstrength which is required in such an appliance.

Inoperation a pair ofzbars 5'. are screwedk upon the. floor of theelevator platform parallel to one another and separated: a distancecorresponding `to the separationofthe legs of a wheel-barrow; Thecastings .l'will then be tightened in place on the bars at one end orthe: other-thereof according to the direction that the` wheel-barrowsare pushed onto the car. The legs tend to'run upA the incline fromeither: side -in-an obvious manner when4 the wheel-'barrow' ispushedinto place and furthertend :to drop vnaturally into the pockets2.V Underr` these circumstances the wheel-barrow is-certa-in tonbeproperly positioned and the workmen are lrelieved'of the usual care andanxiety. When the wheelbarrow is to .be removed, itis readily liftedVoutof the pockets andlcaube pushed orpulled off the carin eitherdirection.
